Sorry to hear this. Are you using iTunes tracks (local music) in your mix? If you are, posting the mix will be disabled because for copyright reasons we can't let you share these tracks.
If you're only using Spotify tracks, looking at our sever there was a small blip with the company we use to store and hold our mixes in the same hour as you've reported this. It should be fixed now - so do try again. Let me know if you still need help.
